r :IQQQEQEEQQ DISPOSABLE SANITARY, COLLAPSIBLE BIDET BACKGROUND OF THE INVENTION Bidets, or sitz baths, are conventionally found in hotel rooms in European countries for feminine hygiene, but such built-in plumbing equipment is not generally found in the United States.

There have been many patents issued on portable bidets of rigid material, usually having a side flange to be detachably supported on the edge of the toilet bowl or on the toilet seat. Typical of such patents are US. Pat. No. 2,427,807 to Oliver of Sept. 23, 1947, US. Pat. No 2,947,995 to Saulson of Aug. 9, 1960, US. Pat. No. 3,365,729 to Perlman of Jan. 30, 1968, US. Pat. No. 3,484,872 to Romberger of Dec. 23, 1969, US. Pat. No. 3,490,079 to Stolbach of Jan. 20, 1970, and US. Pat. No. 3,654,636 to Restyanski of Apr. 11, 1972.

None of the rigid, flanged trays of the above patents are of disposable material, none are collapsible into a small compact package for use in travelling, and none cover, or entirely enclose, the entire toilet seat so that the body cannot touch the same. These rigid receptacles of the prior art would be difficult to carry, even if termed portable, and would be unsightly and perhaps embarrassing if stored in a bathroom.

It has heretofore been proposed in trash and litter receptacles to drape the open end portion ofa thin plastic bag over, and down, the sides of a container, or to clamp the open end around a supporting rim, as in US. Pat. No. 3,002,194 to Wuest of Oct. 3, 1961. However, it will be apparent that it would be most difficult to so drape an unclamped bag over a toilet seat for the reason that the single-ply bag bottom would be resting in water in the toilet bowl and the bag could not be prevented from slipping off the seat into the bowl when filled with hot water. To attempt to clamp the bag in place would require additional parts, such as adhesive, tapes or clamp elements, which would be awkward to use and unlikely to fit the various sizes and shapes of conventional toilet seats.

SUMMARY OF THIS INVENTION In this invention, the disposable collapsible bidet is of limp flexible sheet material and, instead of being rigid flange supported on the edge portion of a toilet seat, it is an open-ended envelope which loosely slides over and entirely encloses the toilet seat. Thus, there is no danger of the body of the user touching any part of the toilet seat, so that it can be safely used in a public rest room, motel bathroom or hospital bathroom. The opposite side walls, or two plies, of the envelope extend in superposed position across the hole in the seat with a predetermined sag because of the loose fit and limp material to form a two-ply dished receptacle at a spaced distance below the level of the seat and above the level of the water in the bowl. Preferably, the envelope is of thin, transparent, water-impervious, plastic film with one side wall longer than the other to form a lip for easy separation of the plies. Preferably also, the forward closed end portion is gussetted, with heatsealed in-folds, to conform to the curve of the seat. Preferably also, there is an air hole in the lower ply, or wall, to admit air to break the suction. The air hole is also used to spray germicide into the envelope when the toilet seat is raised, this being possible when the envelope entirely encloses the seat to satisfy health laws in certain states for motel bathrooms. The disposable bidet of the invention is rollable, or foldable, into a compact package fitting a ladys handbag, or it may be sold in stacks or rolls.

The compact package is merchandised in a water impervious plastic bag forming a receptacle with which to fill the bidet with liquid.

One distinct advantage of the disposable bidet of the invention is that the liquid contents may be discharged into the toilet bowl after use by slidably withdrawing the envelope from the front of the seat, the liquid falling off the gradually sagging open-end portion without wetting the seat.

DESCRIPTION OF A PREFERRED EMBODIMENT A conventional water closet 25 is shown in FIGS. 3-6, mounted against a wall 26 on a floor 27 and having the usual flush tank 28 and toilet bowl 29. The water closet 25 may be of any suitable type and includes a hinged toilet seat 31 supported by the bowl rim 32 and having an annular configuration defining the hole 33, the front portion 34 being curved. A seat cover 35 is usually also attached to the hinge 36. The level of water 37 in the bowl 29 is indicated at 38.

The disposable, sanitary, collapsible bidet 41 of the invention is formed by an enclosure, envelope or bag 42 of flexible sheet material 43, preferably of transparent plastic film 44, having two opposite side walls 45 and 46 folded, or heat sealed, along three peripheral edges 47, 48 and 49. The material 44 may be an opaque woven textile fabric, or any other low-cost, waterimpervious sheet material capable of being discarded after use, although it will be understood that, if desired, it may be re-used again and again and may be of expensive water-impervious material if desired. The material 44 is not rigid, or semi-rigid, but rather is limp, flexible, and capable of sagging, as shown in FIGS. 4 and 5, as well as being capable of being rolled, or folded, into a compact package fitting in a ladys purse.

As shown in FIG. 1, the envelope 42 has a closed end 51 and an open end 52 and, as shown in FIGS. 3-6, the open end 52 and the predetermined width and length of the walls of the envelope 42 are of such dimensions that they may be slid over and around the toilet seat 31 with a loose fit to extend from the front portion 34 to beyond the hinge 36 and thereby entirely cover and enclose the seat so, that the human body cannot contact the same. The predetermined dimensions of envelope 42, and the limp, flexible characteristics of the sheet material 43, are arranged to enable the central portion 53 of envelope 42 to sag downwardly to form a two-ply liquid receptacle or dished depression within the hole 33 at a predetermined spaced distance below the level of seat 31 and preferably above the level 38 of the water 37 in bowl 29. The upper side wall 45 extends over the seat 31, while the lower side wall 46 extends under the seat 31 and over the bowl edge 32, and when the hand of the user, or a supply of hot water, is placed in the central portion 53, the envelope automatically slides around the toilet seat edge to superpose intimately the two wall plys and form a dished, bowl-like depression 59 with the upper ply 54 overlying the lower ply 55 in support of each other to prevent any leakage or tearing despite the low cost disposable nature of the material 43.

Preferably, one side wall 45 or 46 is longer than the other, the resulting integral extension 56 forming a curved lip 57 enabling one side wall to be gripped and separated from the other for slidable fitting of the open end 52 over the seat 31. The lip 57 is preferably on the upper wall to extend over the hinges 36, even if the lower wall is barred by the hinges, to assure complete sanitary covering of the seat. The corresponding edge 58 of the other, or lower, wall is straight.

The lip 57 in the upper wall prevents liquid from enteringthe interior 65 during discharge (FIG.

An air aperture 61 is provided in at least one side wall, preferably the lower wall 46, and located near the closed end 51. As shown in FIG. 6, the aperture 61 helps to break the suction between the walls and does not cause leakage or weakness because it is in the under-ply, or wall, and well above the level 62 of the liquid 63 in the envelope 42 (FIG. 4). The principal purpose of aperture 61 is to enable a motel employee to spray a germicide 64 through the hole into the interior 65 of the envelope to sanitize the seat 31 while it is entirely covered and enclosed by the envelope 42.

In the preferred embodiment, the envelope 42 is not entirely rectangular in configuration but, instead, at least one in-fold, or gusset, 66 or 67 is formed by oblique heat-seal lines 68 or 69 at the closed end 51, in order that the closed end portion may substantially conform to the curved configuration of the front portion 34 of seat 31. It would, of course, be possible to use a pair of suitably curved, or .circular, sheets, heatsealed around the peripheral edges thereof, except at an open end such as at 52, but, while a better and more attractive loose fit would be obtained, there would be a considerable wastage of cut-out material so that the low cost, disposable feature might be lost. The reduced width of the closed end 51, caused by the gusset means 66 and 67, results in a strengthening of the closed end against tearing.

In operation, it will be apparent that the sanitary, disposable bidet of the invention may be loosely fitted over every toilet seat in a public rest room or motel, or the user may have a supply thereof in her hand bag ready for use when needed. The envelope is merely slid over the toilet seat to enclose it completely, whereupon liquid is placed in the bowl-like, two-ply depression 59, and personal hygiene, cleansing and heal treating accomplished without the necessity of disrobing completely. Upon completion, as shown in FIG. 5, the envelope is merely slidably withdrawn slowly, while the liquid 63 discharges from the sagging open end down into the bowl without wettingthe seat. The envelope may then be discarded or dried and re-used, as desired. The envelope could be of any waterproof material, such as treated paper, and formed by folding, sewing, cementing or heat-sealing. v

The disposable bidet of the invention lends itself to use in advertising as a'premium, .or give-away, and tends to prevent infections, contaminations and transfer of contagious diseases. If not used as a disposable bidet, it is still a low cost sanitary toilet seat cover, or lining, differing from conventional covers in enclosing the entire seat, rather than merely covering the upper surface or a portion of the upper surface.

Preferably, as shown in FIG. 4, the disposable bidet 41 is merchandised in a disposable, water-impervious bag 71 of plastic, or the like, which is air tight for sanitation and which may contain several bidets. The bag 71 forms a convenient vessel for filling the bidet with liquid and the entire package, including the bag 71 is easily carried by travelers.

When sealed, bag 71 includes unsealing means 72 along one end 73, such as the tear strip 74 and may also include a plastic zipper closure 75 of known type.
